Las Vegas shooter was retired, had no criminal record

MESQUITE, Nev. – The man who killed 58 people and injured at least 515 others at a Las Vegas concert was a retiree with no criminal history in the Nevada county where he lived, police said Monday.

The brother of Stephen Paddock, 64, said he's "completely dumbfounded" by the shooting at a country music concert Sunday night, the deadliest in modern U.S. history. Eric Paddock told the Orlando Sentinel newspaper that he can't understand what happened.

Stephen Paddock had no connection to an international terrorist group, the FBI said Monday. The announcement from Aaron Rouse, special agent in charge in Las Vegas, comes after the Islamic State group claimed responsibility for the attack without providing evidence.

Paddock owned a single-family home in Sun City Mesquite, a retirement community along the Nevada-Arizona border, Mesquite Police Chief Troy Tanner said.

He lived there with a 62-year-old woman, police said. Authorities said they don't believe she was involved and was out of the country at the time of the shooting but they wanted to speak to her when she returned.

Heavily armed police searched the home early Monday, hours after Paddock killed himself in a room at Mandalay Bay Hotel and Casino where police believe he opened fire on a crowd of 22,000 people.

Paddock bought the one-story, three-bedroom home about 80 miles north of Las Vegas in 2015 for about $370,000, according to property records that list him as a single man.

Authorities in Texas say he lived in a Dallas suburb from 2009 to 2012. Public records indicate Paddock may have lived in Mesquite, Texas, for longer, but police Lt. Brian Parrish said his department's review shows the approximately three-year period.

A preliminary review of police records don't indicate that authorities had any contact with him but police are still investigating, Parrish said.
